Guilty Pledgers

A Spotify-powered app that lets you donate money to charity each time you play a particularly cheesy song.

The fundraising app combines Spotify's song catalogue with Just Giving's charity payments platform to allow individuals to offload the guilt of playing cheesy tunes.
Party hosts can sign in with Facebook, open up a playlist and pick a preferred charity. Attendees can then visit the Guilty Pledgers web app via their mobile and pledge a minimum of £2 in order to add their preferred song to the party playlist.
